UL 2200 Figure 8.2 Probe PA130B for Moving Parts and Uninsulated Live Parts in Engine Generator Assemblies

This UL 2200 Figure 8.2 Probe PA130B is a specialized safety tool designed to test the accessibility of moving parts in stationary and portable generators—such as fan blades, belt pulleys, and motor rotors. It features a rigid stainless steel probe body to simulate accidental user contact, paired with an insulating nylon handle for tester safety. 

Specifications:
Probe Type: UL 2200 Figure 8.2 Probe PA130B (for moving part accessibility testing in generators)
Handle Material:Nylon (fully insulating, heat-resistant up to 110°C; non-slip grip for controlled operation near generator components)
Key Dimensions:
– Straight Finger Diameter: 12.7mm (1/2 inch)
– Straight Finger Total Length: 101.6mm (4 inch)
– The Head Length: 14.3mm (9/16 inch)
– The Head Radius: R 4.8mm (3/16 inch)
– The Tail Diameter: 19.1mm (3/4 inch)

Test Procedures:
1. Inspect the probe for damage (e.g., bent stainless steel body, cracked nylon handle) to ensure structural integrity.
2. Power on the generator and let it reach normal operating mode (ensure all moving parts are active).
3. Hold the insulating handle and align the probe tip with gaps in guards/shields (e.g., around fan covers, pulley enclosures).
4. Apply steady 10N thrust to the probe—stop immediately if resistance from moving parts is felt.
5. Check if the probe touches any rotating components (e.g., blades, pulleys) or bypasses safety guards.
6. Record whether the generator meets safety requirements (pass/fail) and power off the unit.

Applications:
1. Safety testing of portable gasoline generator fan blades (per UL 2200:2023 Figure 8.2) to ensure guard effectiveness.
2. Verification of industrial generator motor rotors to prevent access to rotating parts in manufacturing facilities.
3. Quality control for small inverter generator cooling fan guards during production.
4. Post-production audits of emergency backup generator moving part shields to meet UL 2200 safety standards.
